Docker Compose Server on Ubuntu Server 20.04

Docker Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a YAML file to configure your applications services. Then, with a single command, you create and start all the services from your configuration.

Docker compose is a simple yet powerful tool that is used to run multiple containers as a single service. For example, suppose you have an application which requires Nginx as a web server and PostgreSQL as a database service. In this case by docker-compose, you can create one single file (docker-compose.yml ) which will create both the containers as a single service without starting each separately

When youre developing software, the ability to run an application in an isolated environment and interact with it is crucial. The Compose command line tool can be used to create the environment and interact with it.

The Compose file provides a way to document and configure all of the applications service dependencies (databases, queues, caches, web service APIs, etc). Using the Compose command line tool you can create and start one or more containers for each dependency with a single command (docker-compose up).

How does Docker Compose work?

1. Use yaml files to configure application services (docker-compose.yaml)
2. Can start all the services with a single command ( docker-compose up )
3. Can stop all the service with a single command ( docker-compose down )
4. Able to scale up the specific services when required
5. Works in all environments: production, staging, development, testing, as well as CI workflows
